CLAMP.

- Application filed October 19, 1922. Serial No. 595,508.

To all whom it may concern:

Be it known that I, CHARLES C. TOMKIN- soN, a citizen of theUnited States, and a resident of Plainfield, county of Union, and State of New Jersey, have invented certain new and useful Improvements in Clamps, of which the following is a specification.

This invention relates to clamps and more particularly to devices for clamping together two or more strips of timber.

In building construction work where staging is used, in order to secure braces of adequate strength it is often necessary to secure together two or more strips of timber. This is ordinarily done by nailing the strips together. This method of securing is objectionable since the strips are often broken when they are separated and, moreover, it requires the expenditure of a considerable amount of time to nail them together and to separate them. i

This invention has for its object to provide a device for effectively clamping strips of timber together and, further, to provide a device of this character that may be easily and quickly applied to and detached from the timbers.

Another object of the invention is to provide a clamp of the character described that will firmly secure together the parts engaged thereby. V

Another object of the invention is to provide a timber clamp that is simple but rugged in construction and may be economically manufactured.

Further objects of the invention will appear from the following specification taken in connection with the drawings, which form a part of this application, and in which- Fig. 1 is an elevational view showing iii section one form of the invention, this view being taken substantially on line 1 1 of In order to secure the strips of timber between the connecting portion 13 and the rod 15, a wedge 16 is interposed between the rod 15 and the timber strip. The wedge may be driven in to a sufiicient extent to securely and firmly hold the strips of timber in the clamp.

As shown in Fig. 1, the wedge 16 has formed thereon an upwardly extending lug 117 by1 means of which the wedge may be reeasec. I

From the foregoing specification it will be seen that very simple and practical timber clamp has been devised and that the clamp may be easily applied to or detached from'the objects in connection with which it is used.

Although one specific embodiment of the invention has been particularly shown and described it will be understood that the invention is capable of further modification and that further changes in the construction and arrangement of the cooperating parts may be made without departing from the spirit or scope of the invention.

What I claim is:

l. A clamp comprising a substantiailly U-shaped member, having hooked ends, a connecting member adapted. to engage said ends and an adjustable member adapted to engage said connecting member and to clamp objects in said Ushaped member.

2. A clamp comprising a substantially U-shaped member, having curved ends, a connecting member adapted to engage said ends, and an adjustable wedge member adapted to engage sald connectlng member and to clamp objects in said U-shaped member.

3. A clamp comprising a U-shaped member having oppositely disposed offset portions on the legs thereof, a cross member CHARLES C. TOMKINSON.
